Answer:
b=-2aH
Step-by-step explanation:
H=-b/2a
Apply cross multiplication
H×2a=-b
2aH=-b
In the question you are to find positive b not negative b so you have to take negative b to the left hand side of the equation to become positive b and take 2aH to the right hand side to become -2aH
therefore b=-2aH
If you mean h(4)
h(4)=(4)*2 -5(4)
=8-20
=-12
The answer will be-12
Y is behind 2 its in plain sight
